But now the new site link will (as soon as the DNS propagates) be "broken" instead.
All other languages have 2 domains: one for the old site and a different one domain for the new site. I'm not sure if italian was like this before, but right now I don't know if there are 2 domains for it.
The only thing I can guarantee you is it was nothing I did or could have done. I have no access to the old site and I haven't touched anything here since before April 9th. Plus the new site links were all working fine.
